Answer:
E. Vasoconstriction.
Explanation:
Vasoconstriction is narrowing or constriction of the blood vessels. It happens when smooth muscles in blood vessel walls tighten. This makes the blood vessel opening smaller. Vasoconstriction may also be called vasospasm.
Vasoconstriction is a normal process. It helps keep your body in healthy balance.
Vasoconstriction may occur to:
stabilize blood pressure or raise blood pressure
reduce loss of body heat in cold temperatures
control how blood is distributed throughout your body
send more nutrients and oxygen to organs that need them
protect your body against blood and fluid loss
Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole.
The Clean Air Act authorizes the U.S. Environmental Protection Agency (EPA) to protect public health by regulating the emissions of these harmful air pollutants. The NRDC has been a leading authority on this law since it was established in 1970.
What Causes Air Pollution?
“Most air pollution comes from energy use and production,” says John Walke, director of the Clean Air Project, part of the Climate and Clean Air program at NRDC. “Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walke says. “Another type of air pollution is then worsened by that increased heat: Smog forms when the weather is warmer and there’s more ultraviolet radiation.” Climate change also increases the production of allergenic air pollutants including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season and more pollen production).
The answer Is A.
<em></em>Iron Deficiency will most likely impair a child growth and his/her overall learning abilities.
While most people focusing on protein and calcium for their child's growth, often time they forget about iron, which have a very important role in defining bone structure.
an iron deficiency will also lower the amount of our blood cells which will lead to Anemia, causing a constant fattigue, nausea, and dizziness and lower the childs mood, attention span, and ability to learn
